Fua mole mole oloa:
N,N-Dimethylformamide o se vai e leai se lanu po o sina samasama samasama ma le vevela o le 153 ° C ma le mamafa o le ausa o le 380 Pa i le 20 ° C. E solu fua ile vai ma solu ile ava malosi, acetone ma benzene. N, N-Dimethylformamide o loʻo faʻaaogaina e pei o le solvent, catalyst ma le gas absorbent. Fa'aoso fa'amalosi ile sulfuric acid concentrated, fa'a'asa ole nitric acid ma e mafai fo'i ona pa. O le Dimethylformamide mama e leai se manogi, ae o le tulaga fale gaosi oloa po'o le Dimethylformamide ua suia e iai lona manogi i'a aua o lo'o i ai mea leaga ole Dimethylamine. Dimethylformamide e le mautu (aemaise i le maualuga o le vevela) pe a iai se faʻavae malosi e pei o le sodium hydroxide poʻo se malosi malosi e pei ole hydrochloric acid poʻo le sulfuric acid, ma e faʻafefeteina ile formic acid ma le dimethylamine.
N,N-Dimethylformamide (DMF) o se vai manino ua faʻaaogaina lautele i alamanuia e pei o se solvent, se faʻaopoopoga, poʻo se vaeluagalemu ona o le tele o le miscibility i le vai ma le tele o vaifofo masani masani.
O le Dimethylformamide e masani ona faʻaaogaina e avea o se solvent alamanuia. Dimethylformamide fofo o loʻo faʻaaogaina e faʻaogaina ai filo polymer, ata tifaga, ma faʻapipiʻi luga; ia fa'ataga faigofie le milo o alava acrylic; e gaosia ai uaea enamels, ma avea o se auala crystallization i le alamanuia vailaau.
E mafai foʻi ona faʻaaogaina le DMF mo le faʻaogaina ma le alkyllithium poʻo le Grignard reagents.
O lo'o fa'aaogaina e fai ma sui i le Bouveault aldehyde synthesis fa'apea fo'i i Vilsmeier-Haack reaction. E galue o se faʻamalosi i le faʻapipiʻiina o acyl chlorides. E fa'aaogaina mo le tu'ueseeseina ma le fa'amamaina o le kasa olefin. DMF faʻatasi ai ma le methylene chloride e galue e pei o se aveeseina o varnish poʻo lacquers. E faʻaaogaina foi i le gaosiga o mea faʻapipiʻi, filo ma ata tifaga.
N,N-Dimethylformamide (DMF) o se solvent e maualalo le fua o le fa'asao, aoga mo le saunia o vaifofo fa'atasi ai ma le tele o vaila'au fa'aletino hydrophobic o lo'o fa'aaogaina i le molecular biology applications.
N, N-Dimethylformamide na faʻaaogaina e solubilize MTT tioata i suʻesuʻega gafatia sela. Na faʻaaogaina foi i le feruloyl esterase faʻataʻitaʻiga faʻataʻitaʻiga i faʻataʻitaʻiga e faʻaalia ai le maualuga o le gaioiga o le enzyme.
O le fa'aaogaina o le DMF i le lalolagi atoa i le 2001 e tusa ma le 285,000 metric tone ma o le tele o na mea sa fa'aaogaina e fai ma so'o fa'ameamea.
E mafai e Chemwin ona tuʻuina atu le tele o vailaʻau hydrocarbons ma vailaʻau vailaʻau mo tagata faʻatau pisinisi.Aʻo leʻi faia lena mea, faʻamolemole faitau faʻamatalaga autu nei e uiga i le faia o pisinisi ma matou:
1. Puipuiga
O le saogalemu o la tatou faamuamua sili. I le faaopoopo atu i le tuʻuina atu i tagata faʻatau faʻamatalaga e uiga i le saogalemu ma le faʻaogaina o le siosiomaga oa matou oloa, matou te tuuto atu foi i le faʻamautinoaina o le saogalemu o lamatiaga o tagata faigaluega ma konekarate e faʻaitiitia i se tulaga talafeagai ma mafai. O le mea lea, matou te manaʻomia le tagata faʻatau e faʻamautinoa ua ausia tulaga talafeagai o le laʻuina ma le teuina o le saogalemu aʻo leʻi tuʻuina atu (faʻamolemole vaʻai i le faʻaopoopoga HSSE i aiaiga lautele ma aiaiga o faʻatau i lalo). O matou tagata tomai faapitoa i le HSSE e mafai ona tuʻuina atu taʻiala i nei tulaga.
2. Tuuina atu auala
E mafai e tagata fa'atau oloa ona fa'atonu ma tu'uina atu oloa mai le chemwin, pe mafai fo'i ona latou maua oloa mai le matou fale gaosi oloa. O auala o felauaiga o lo'o avanoa e aofia ai loli, nofoaafi po'o felauaiga tele (tulaga eseese e fa'atatau).
I le tulaga o manaoga o tagata faatau, e mafai ona matou faʻamaonia manaʻoga o vaʻa poʻo vaʻa ma faʻaoga tulaga faʻapitoa mo le saogalemu / iloiloga ma manaʻoga.
3. Ole aofa'i ole oka la'ititi
Afai e te faʻatau oloa mai la matou upega tafaʻilagi, o le aofaʻi aupito maualalo ole oka ole 30 tone.
4. Totogi
Ole auala masani ole totogi ole toesega tuusao ile 30 aso mai le pili.
5. Tuuina atu pepa
O pepa nei o lo'o tu'uina atu i fa'asalalauga ta'itasi:
· Bill of Lading, CMR Waybill po'o isi pepa felauaiga talafeagai
· Tusi Faamaonia o Suʻesuʻega poʻo Faʻatatau (pe a manaʻomia)
· Fa'amaumauga e feso'ota'i i le HSSE e tusa ai ma tulafono fa'atonutonu
· Fa'amaumauga a le Ofisa o Tiute e tusa ai ma tulafono fa'atonutonu (pe a mana'omia)
